I have two 4 blade ACME props that I was hoping to be able to use for my boat, but unfortunately I will not. I have one 13.25 x 16 number 645 and one 14.5 x 14.25 1 1/8", number 1235 prop. I believe they were originally intended for a CC boat, but neither one have even been on a boat. I have had them for about 3 years and have been using them as decorations. There is absolutely nothing wrong with either prop. I only have a pic of the 14.5 prop as the other is at the lake. If you are interested, please let me know.
